Having the same issue here. Could someone help me out? I swapped the HDD with another (used) one and am having the same exact behavior. Thanks!
You need, versions:
New boot SD card (from xerox)
Your own SD card not more than 8GB (better 4Gb 10 class), Linux command line, image of original boot SD card.
New or used HDD 500GB (better SSD min 128GB, bigger-better)
Just replace old with new and make ALTBOOT
